Method Details
-
createUI
Returns a UI.- Parameters:
c- a component- Returns:
- a UI
-
getContext
Returns the Context for the specified component.- Specified by:
getContextin interfaceSynthUI- Parameters:
c- Component requesting SynthContext.- Returns:
- SynthContext describing component.
-
update
Notifies this UI delegate to repaint the specified component. This method paints the component background, then calls thepaint(SynthContext,Graphics)method.In general, this method does not need to be overridden by subclasses. All Look and Feel rendering code should reside in the
paintmethod.- Overrides:
updatein classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- the component being painted- See Also:
-
paint
Paints the specified component according to the Look and Feel.This method is not used by Synth Look and Feel. Painting is handled by the
paint(SynthContext,Graphics)method.- Overrides:
paintin classComponentUI- Parameters:
g- theGraphicsobject used for paintingc- the component being painted- See Also:
-
paint
Paints the specified component.- Parameters:
context- context for the component being paintedg- theGraphicsobject used for painting- See Also:
-
paintBorder
Paints the border.- Specified by:
paintBorderin interfaceSynthUI- Parameters:
context- a component contextg-Graphicsto paint onx- the X coordinatey- the Y coordinatew- width of the borderh- height of the border
-
paintTrack
Paints the scrollbar track.- Parameters:
context- context for the component being paintedg-Graphicsobject used for paintingtrackBounds- bounding box for the track
-
paintThumb
Paints the scrollbar thumb.- Parameters:
context- context for the component being paintedg-Graphicsobject used for paintingthumbBounds- bounding box for the thumb
-
getPreferredSize
A vertical scrollbar's preferred width is the maximum of preferred widths of the (nonnull) increment/decrement buttons, and the minimum width of the thumb. The preferred height is the sum of the preferred heights of the same parts. The basis for the preferred size of a horizontal scrollbar is similar.The
preferredSizeis only computed once, subsequent calls to this method just return a cached size.- Overrides:
getPreferredSizein classBasicScrollBarUI- Parameters:
c- theJScrollBarthat's delegating this method to us- Returns:
- the preferred size of a Basic JScrollBar
- See Also:
-
propertyChange
Description copied from interface:PropertyChangeListenerThis method gets called when a bound property is changed.- Specified by:
propertyChangein interfacePropertyChangeListener- Parameters:
e- A PropertyChangeEvent object describing the event source and the property that has changed.
